Spent some time today thinking through how to use cameras to remotely monitor monarch clusters.
I came up with this design, which I illustrated using Rhino. The file can be found on my Althouse and Meade OneDrive, but should probably be moved to the github.
Basic idea here is to be able to mast up the modified camera and wind logger to get close to the butterflies. In my illustration, I have it on a tripod, but after a bunch of research, I'm now thinking I should use guy lines and a masting pole.
Here are some videos that influenced my thinking:

I particularly like this guy's setup, where uses guy lines to keep the pole in place:
They look strong, and can be used with power tools, which will be a big help in the field. There are many like this, so worth exploring a bit.
For the masting pole, I explored widely, but found this 50ft pole that has really thought through the problem:
It's not cheap, but there should be budget. Also having the extra height should be very useful, as monarchs can easily be above 30ft.
All necessary accessories are offered on the site, and they offer bulk discounts. I'm thinking I order 10 and call it a day.
I spent some time with chatGPT to elvauate how to guy the mast. Here are the summary points:

From the website, they recommend dacron, which is resistant to stretching. I think I can buy all the guying accessories from the site and have just one order purchase.
